Well goofing off here at work, I looked up the owners manual for the filter and it states not to use pipe dope and only use teflon tape. It states to use no more than 7 wraps.

Reading thru this thread, I probably over tightened because I threaded the fitting all the way till it wouldn't go any further (you can see that in the photo). Tonight I will put in some unions so that I am able to dissemble - looking a the photo, you will see there is no way to unthread as is without removing the wall (my bad). I will look for the thicker tape and re-do. I know that I have, at home the heavy duty dark grey tape at home.

Regardless, I'm on the home stretch and was able to take a hot shower this morning - using buckets of water on the driveway was not fun over the weekend. Crawling under the house about 50+ times for re-plumbing the gas lines and water was not fun either. I was very surprised how quiet the tankless is - it barely makes a sound.
